Every model is going to be different. If your fuel tank is on the CG you need to be really careful. If your fuel tank is in the nose, it gives you a little margin for error. Taking off with a full tank will help with nose weight. So if the plane starts to act tail heavy as it burns fuel you know it is to tail heavy.
If it was me doing it. I would add some temporary weight to get the CG at 110 and put a few flights on it. Then, if you are comfortable with the handling, try it without the weight. Keep in mind also that a rearward CG can make a plane very hard to land. I have owned one that every landing was like a harrier. It made every landing a controlled crash.
